We divide 870661 by 19
The aim is to understand the frequency of 19 in 870661.

Step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 19

Going ahead to step 2:
The number 19 fits into 87 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 76 from 87 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 19

Let's proceed to step 3:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 95 from 110 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 19

Step 4:
19 can be fit into 156 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 458.0
Subtracting 152 from 156 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 19

Going ahead to step 5:
If we divide 46 by 19, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4582.0
The remainder is 8 after subtracting 38 from 46.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 19

Going ahead to step 6:
The number 19 fits into 81 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 45824.0
The remainder is 5 after subtracting 76 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 45824.2
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 19, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 45824.26
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 19, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 45824.263
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
19 goes into 30 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 45824.2631
If we take 19 away from 30, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 45824.26315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
150 divided by 19 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 45824.263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
19 goes into 170 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 45824.2631578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 45824.26315789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 45824.26315789, and the remainder is 9e-09.
